I carriesa rail 11 whichreceives the line of 50 To these and other endsthe invention 0011- matrices when the second elevator is in its sists incertain improvements and combinalowerposition, and when the second elevations and arrangements of parts all as will tor rises, this rail 11 and matrices suspended be hereinafter more fully described, the featherefrom come into alinement with a simitures of novelty, being pointed out particu lar rail l2arranged at the entrance to the 55 larly in the claimed; p matrix dist'ributinggmechanism. The ad-- jacent ends of the rails 11 and 12 are beveled so that when they are alined for the transfer of the matrices to the rail 12, a diagonal joint 13 is formed between them. When the second elevator has ascended to the point where the matrix supporting rail 11 is alined with the rail 12, a pusher operates to transfer the line of matrices from the rail 11 onto the rail 12. This pusher usually comprises a follower 14 to engage behind the line of matrices, a slide 15 which guides and supports the follower, a link 16 which is connected to the slide, and an arm or lever 17 which is connected to the link and is supported on the machine so as to swing to and'fro about the aXis 18, it having suitable means on the main shaft 2 for reciprocating it at appropriate times. These parts just described comprise a shifting de vice for transferring thematrices from the second elevator to the distributer.

Heretofore, in machines of this type, obstruction to the entrance of the matrices into the distributer caused one or more of the matrices to occupy a position where it lapped the rails 11 and 12 or extended across the diagonaljoint 13 between these rails, and thisprevented descent of the second elevator, although the main shaft continued to revolve to a point where the high portion of the cam 6 receded or disengaged from the roller 10. l'leretofore, the machine would be stopped because of the failure of the second elevator to descend, but such stopping of the machine did not take place until after the cam 6 had receded or moved out of contact with the roller 10. In machines as heretofore constructed, it was necessary to provide -'a safety latch comprising the hooked members 19 and 20, it being necessary to engage this safety latch to hold the second elevator 7; it was then necessary to go to the front of the machine and lock the transfer mechanism; it was necessary next to remove the obstructing matrix or matrices, and thereafter to release the safety latch 19, 20 and finally lower the second elevator gently by hand.

Thepresent invention provides means which is controlled according to the position of the distributor shifting device which transfers the matrices from the second elevator to the distributer, the controlling means of the present invention operating automatically to stop the machine in case of an. obstruction such as that just described,

at a time which will avoid receding of the cam 6 from the roller 10 which actuates the second elevator, the controlling or stopping device of the present invention also embodying means whereby the machine may be restarted directly and with facility after the obstruction has been removed. .As shown,

the lever orarm 17 ofthe matrix shifter is provided with apin or projection 21 and a lever 22 is provided, this lever being pivoted at 23 on a portion of the frame of the machine and one arm of the lever is provided with a surface 24 on which the pin or projection rides during the to and fro swing of the shifter arm 17, this surface having outer and inner recesses or depressions 25 and 26, spaced thereon in a manner that will hereinafter appear. The opposite end of the lever 22 is connected by a rod 27 to a pawl 28 having a notch 29 adapted to engage a dog or projection 30 carried by the main shaft 2, when the pawl 28 is in its lower position, the dog clearing the pawl 28 when the latter is elevated. The pawl 28 is pivotally connected at 31 to the upper end of a lever 32, the latter being pivoted at 33 on the main frame and its lower end is adapted to bear against the arm 5 of the main clutch shifting fork 8.

The surface 24 and the notch 25 are so related to the pin or projection 21 on the shifter arm 17 that when the pin engages either the surface 24 or in the notch or depression 25, the pawl 28 will occupy its lower position and the dog 30 which revolves with the main shaft will engage the notch or shoulder 29 of the pawl, pushing the latter longitudinally in the direction indicated by the arrow in Fig. 1 and rocking the lever 32, the lower end of this lever operating upon the arm 5 of the clutch shifting fork 3, and the latter operating to disengage the main driving clutch of the machine. The position of the pin 21 on the shifter arm 17 is such that it will engage the surface 24 or the notch or depression 25 when the follower 14 occupies a position where all the matrices have not been transferred from the rail 11 onto the rail 12. This would occur in case the entrance of the matrices into the distributor were obstructed. The step, notch or depression 26 of the lever is so located with respect to the pin 21 that when the pin 21 recedes in this recess or depression, the follower 14 which transfers the matrices from the rail 11 to the rail 12 has completed its stroke and consequently completed the transfer of the matrices. The arrangement of this step, notch or depression 26 is also such that when the pin 21 rests therein, the pawl 28 will be held elevated sufficiently to permit the dog 30 to pass beneath it, without, however," actuating the pawl to disengage the clutch. The dog 30 is so placed on the main shaft 2 with relation to the second elevator cam 6, that the stopping of the machine will occur prior to movement of the cam out of engagement with the roller 10. As the cam 6 remains in engagement with the roller 10, the second elevator is supported in its elevated position, and after the obstructing matrices have been removed, it is only necessary to lift the pawl 28 out 1 driving clutch, the combination of a distributer for conducting matrices to their respective channels of a magazine, an elevator for conveying matrices to the distributer, means for transferring matrices from said elevator to the distributer, and means controlled by said matrix transferring means for disengaging the clutch. a

2. In a machine of the linotype class having a main driving clutch, the combination of a matrix distributer, an elevator for lifting matrices to the distributer, a slide for shifting matrices from said elevator to the distributer, and automatic means controlled by the position of said slide for disengaging the main clutch.

3. In a line casting machine having a main driving clutch, the combination of a matrix distributer, an elevator for lifting matrices from a lower level to the distributer, a cam for lifting said elevator, a shifter for transferring the matrices from the elevator to the distributor, and means controlled automatically by the shifter for disengaging the main driving clutch while the cam holds the elevator in its upper position. 40

4:. In a machine of the linotype class having a main driving clutch, a cam driven thereby, a matrix elevator actuated by said cam, and a matrix distributer to receive matrices from the elevator, the combination of a shifter for transferring matrices from the elevator to the distributor, and means controlled according to the position of the shifter for disengaging the main driving clutch while said cam is in coopera-tive relation with the elevator.

5. In a machine of the linotype class hav ing a matrix distributer, an elevator for conveying matrices thereto, a cam for actuating said elevator, and a clutch for driving the same, the combination of a device for transferring matrices from the elevator to the distributor, a dog movable with and positioned in predetermined relation with the cam, and means positioned relatively to 6 said dog by said transferring device according to the position of the latter, said means when engaged by the dog operating 0 to disengage said clutch.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
